BEDSTEAD CORNER-FASTENING.

Specification of Letters Patent.

Patented Apr. 20, 1920.

Application filed July 16, 1919. Serial No. 311,259.

To all whom it may concern:

Be it known that I, MORRIS SoHLnsINcnR, a citizen of the United States,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in BedsteadCorner-Fastenings, of which the following is a specification.

The present invention relates to bedstead corner-fastenings, that is tosay to a device for coupling the side-rails of bedsteads to thecorner-posts thereof. More particularly, the invention pertains tocorner-fastenings applicable especially to wooden bedsteads, havingcorner-posts of quadrangular crosssection.

The main object of the invention is to provide a corner-fastening, thetwo locking members of which are exactly alike in construction, wherebya simple and inexpensive device is obtained that can be manufactured ona commercial scale or, in other words, one which is not so difficult toproduce as to be beyond the reasonable cost of such a contrivance.

Another object of the invention is to so devise the fastening that theside-rails are adapted to closely abut against the corner posts, withoutnecessitating the provision of mortises in the said posts.

/Vith these and other objects in view, which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrangement and construction of parts hereinafterdescribed, pointed out in the appended claim and illustrated in theaccompanying drawings, it being understood that many changes may be madein the size and proportion of the several parts and details ofconstruction within the scope of the appended claim without departingfrom the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated inthe accompanying drawings, in which Figure 1 is a sectional view takenthrough one of the corner-posts and side-rails of a bedstead, with thefastening in position thereon; Fig. 2 is a side elevation of the twomembers of the fastening, in engagement; Fig. 3 is a front elevation ofone member of the fastening; Figs. 4, 5 and 6 are sections taken, intheir order, on lines 4L4, 55 and 6-6 of Fig. 3; and Fig. 7 is aperspective view of the two members of the fastening, disengaged.

In the drawings, the numeral 10 indicates one of the corner-posts of abedstead, said corner-post being of quadrangular crossseotion. Againstthe inner face 11 of the post abuts one of the side-rails 12 of the bedframe. This side-rail is made in the form of a wooden board, provided inits end, that is juxtaposed to the face 11 of the corner post, with avertically extending mortise 13. lVithin this mortise are disposed themembers 1 1 and 15 of the corner-fastening, the member 14 being attachedto the cornerpost and the member 15 to the side-rail. These two membersare exactly alike in construction, but inverted in relation to eachother, as will hereinafter appear.

Each fastening member comprises a metallic plate 16 of oblongconfiguration, that is adapted to be attached to the respective elementof the bedstead by screws 17, the heads 18 of which are countersunk, soas not to interfere with the other element of the fastening. In thelongitudinal axis of the plate 16 is disposed a dove-tailed lug 19 ofoblong configuration, the thickness of the said lug corresponding to thethickness of the plate, thereby permitting the lug to be disposed whollyin the plane of the plate. The free edge 20 of the lug is undercut, asclearly shown in Fig. 6 of the drawings, and so is the transverse edge21 of the body portion of the plate adjacent the said lug. From the bodyportion of the lug projects outward a fiat projection 22, the thicknessof which corresponds exactly to the thickness of the plate, or, in otherwords, the plate has a double thickness at the said projection. Thisprojection extends from the transverse edge 23 of the plate 16 towardand beyond the transverse center line of the said plate, and is providedfin the longitudinal axis of the latter with the dovetailed groove 24;,its transverse edges 25 ad jacent the transverse center line of theplate being undercut, as clearly shown in Fig. 6

of the drawings. The transverse edge 26 of the groove in proximity ofthe transverse edge 23 of the plate 16 is also undercut. The size of thegroove is such as to be adapted to receive the lug of the other platemember of the fastening.

One of these plates is secured to the face coinciding withthelongitudinal axis of the face 11 and its lug 19 projecting upward.

The other member of the fastening is disposed within the mortise 13 ofthe rail 12, its longitudinal axis running vertically and its lug 19projecting downward. In other words, the two members are fastened to thetwo elements of the bedstead in inverted positions relative to eachother.

In order-to mount the rail upon the corner'post, the former. is broughtinto abutment with the face 11 of said post above the lug 19 of themember 14, and then allowed to slide downward, whereby the lug 19 of themember 14 is seated in the groove 24 of the member 15 and the lug 19 ofthe member 15 slides into the groove 24 of the member 14. The mortise 13is of a width that corresponds to the width of a member of thefastening, and of a depth that corresponds to the thickness of the plate16 at its fiat projection 22. Owing to this arrangement, the two membersof the fastening are guided as they slide one into the other. Inasmuchas the lugs and grooves of the two members of the fastening aredove-tailed, and also because the edges 20, 21, 25 and 26 of the twomembers are undercut, the rail is securely held upon the bedstead andprevented from movement in all directions, that is to say it is safelyheld against downward movement, longitudinal movement and transversemotion;

By raising the side-rail, the two members of the fastening aredisengaged," thereby disconnecting the rail from the post.

Inasmuch as the depth of the mortise 13 corresponds to the thickness ofa plate member at its fiat projection 22, the fastening is whollyconcealed from view.

What I claim is: V

A corner-fastening for bedsteads comprising two members, eachconsistingof a plate having a clove-tailed oblong lug at one of itsends, the thickness of said lug corresponding to the thickness of saidplate, said lug being wholly disposed in the plane of said plate, and aflat projection on said plate provided with a dove-tailed groove, saidprojection extending throughout the width of said plate from itsv endopposite said lug toward and terminating at about the transverse centerline of said plate, the thickness of said pro ection corresponding tothe thickness of said plate, said two members being arranged inopposition to each other with their projections in abutment with eachother and their lugs seated in the groove of the other member of thefastening.
